Reid Spencer 8dabca4118 Clean up ConstantFoldCastInstruction. 
llvm-svn: 32672
 2006-12-19 07:41:40 +00:00
Reid Spencer f5fc34ad09 Rewrite ConstantFoldCastInstruction so that it doesn't use any of the 
ConstRules. Remove the casting rules from ConstRules and subclasses. This
cleans up ConstantFolding significantly. Passes all tests.

llvm-svn: 32671

Reid Spencer 56fd357f5e Back out last revision, a bit premature, its not an upgrade-only change.

llvm-svn: 32666
 2006-12-19 02:03:04 +00:00
Evan Cheng 9ad6edf2ec May need to promote the operand (either sign_extend_inreg or and) before 
expanding a {s|u}int_to_fp.

Reid Spencer b799e77547 Correct the description of ConstantInt::isValueValidForType. 
llvm-svn: 32664
 2006-12-19 01:34:39 +00:00
Reid Spencer e733472221 Make ConstantInt not care about sign any more. To ensure the AsmParser can 
still check the validity of signed values an overload to isValueValidForType
was added to allow passing in an int64_t to check.

Rafael Espindola 3ab9256d19 macros -> Inline functions 
Lauros's patch

llvm-svn: 32656
 2006-12-18 11:07:09 +00:00
Reid Spencer e45ac2ab11 Remove the createInferredCast methods now that their last uses have been 
removed. All casting is now explicit and not inferred by VMCore.

llvm-svn: 32655
 2006-12-18 08:52:59 +00:00
Reid Spencer 668d90f289 Convert the last uses of CastInst::createInferredCast to a normal cast 
creation. These changes are still temporary but at least this pushes
knowledge of signedness out closer to where it can be determined properly
and allows signedness to be removed from VMCore.

llvm-svn: 32654
 2006-12-18 08:47:13 +00:00
Reid Spencer 4800c38a75 Remove the two-argument (inferred cast) form of ConstantExpr::getCast now 
that its last uses have been removed.

llvm-svn: 32653
 2006-12-18 08:18:46 +00:00
Reid Spencer b83593e3ea Convert the last use of two-argument ConstantExpr::getCast into another 
form so we can remove that method from ConstantExpr.

llvm-svn: 32652
 2006-12-18 08:16:27 +00:00

llvm-svn: 32648
 2006-12-18 03:37:18 +00:00
Reid Spencer 0e60d55519 Add a couple little tests for SExt/ZExt of constants of a sign that doesn't 
match.

llvm-svn: 32647
 2006-12-18 01:11:46 +00:00
Reid Spencer 776311e000 Remove the last use of getUnsignedVersion and getSignedVersion from VMCore. 
ConstantInt doesn't care about the sign of the type it represents. It only
cares about the bitwidth so there is no need to make the sign of the type
match the SExt or ZExt constant expression.

llvm-svn: 32646
 2006-12-18 01:11:03 +00:00

llvm-svn: 32644
 2006-12-17 21:04:02 +00:00
Reid Spencer 8bd6317823 Use a predicate function to identify bitcast of fp and integer instead of 
repeating the logic in two different parts of the code.

llvm-svn: 32643
 2006-12-17 20:24:50 +00:00
Reid Spencer 174dc2f35e Fix PR1058: 
Generate the BITCAST_TEMPORARY regardless of the uses or inlinability of
the instruction. This temporary is needed to perform the instruction, not
provide storage for its results.

llvm-svn: 32642
 2006-12-17 18:50:51 +00:00
Bill Wendling 3307244ce9 Added example of how to code print() methods so that they will disappear 
from the code if "cnull" is passed into them.

llvm-svn: 32638
 2006-12-17 11:11:10 +00:00
Reid Spencer cb80954483 Fix problems in the CBE and InstructionCombining which use the isMaxValue 
and isMinValue methods of ConstantInt. These have been broken since the
isSigned parameter was added. It is necessary to use the signed version
of the type in the call to isValueValidForType or else incorrect results
are returned.

llvm-svn: 32637
 2006-12-17 06:07:30 +00:00
Bill Wendling a77f14265b Added an automatic cast to "std::ostream*" etc. from OStream. We then can 
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.

llvm-svn: 32636

Chris Lattner fd5f03ec3f when inserting a dummy argument to work-around the CBE not supporting

Evan Cheng 4c306ae0c2 Fix a long-standing spiller bug: 
If a spillslot value is available in a register, and there is a noop copy that
targets that register, the spiller correctly decide not to invalidate the
spillslot register.

However, even though the noop copy does not clobbers the value. It does start a
new intersecting live range. That means the spillslot register is available for
use but should not be reused for a two-address instruction modref operand which
would clobber the new live range.

When we remove the noop copy, update the available information by clearing the
canClobber bit.

Reid Spencer 74a528b427 Fix a bug in EvaluateInDifferentType. The type of operand should not be 
used to determine whether a ZExt or SExt cast is performed. Instead, pass
an "isSigned" bool to the function and determine its value from the opcode
of the cast involved.
Also, clean up some cruft from previous patches.

Chris Lattner f4646a7e54 Another step forward in PPC64 JIT support: we now no-longer need stubs 
emitted for external globals in PPC64-JIT-PIC mode (which is good because
we didn't handle them before!).

This also fixes a bug handling the picbase delta, which we would get wrong
in some cases.

Chris Lattner 216c3028e6 * Eliminate calls to CastInst::createInferredCast. 
* Add support for promoting unions with fp values in them.  This produces
   our new int<->fp bitcast instructions, implementing
   Transforms/ScalarRepl/union-fp-int.ll

As an example, this allows us to compile this:

union intfloat { int i; float f; };
float invsqrt(const float arg_x) {
    union intfloat x = { .f = arg_x };
    const float xhalf = arg_x * 0.5f;
    x.i = 0x5f3759df - (x.i >> 1);
    return x.f * (1.5f - xhalf * x.f * x.f);
}

into:

_invsqrt:
        movss 4(%esp), %xmm0
        movd %xmm0, %eax
        sarl %eax
        movl $1597463007, %ecx
        subl %eax, %ecx
        movd %ecx, %xmm1
        mulss LCPI1_0, %xmm0

        movl 8(%esp), %eax
